[0031] See also Figure 1 to Figure 2 As shown, the utility model discloses a specific embodiment of a range-extending mechanism, comprising: a moving base 10, a range-extending slide rail 20, a range-extending movable plate 30, a support assembly 40 and a range-extending lever 50, the range-extending slide rail 20 is installed on the moving base 10, the range-extending movable plate 30 is slidably connected to the range-extending slide rail 20, the support assembly 40 is movably connected to the range-extending movable plate 30, one end of the range-extending lever 50 is hinged to the moving base 10, and the other end is connected to the range-extending movable plate 30, and the range-extending lever 50 is rotated to make the range-extending movable plate 30 move along the range-extending slide rail 20.

[0032] Specifically, both sides of the motion base 10 are provided with extended-range slide rails 20 along the front-to-back direction, the extended-range movable plate 30 is slidably connected to the extended-range slide rails 20 through sliding blocks, the support assembly 40 is used to receive objects (i.e., trays), one end of the extended-range lever 50 is hinged to one side of the motion base 10, i.e., below the extended-range slide rail 20, and the other end is connected to the extended-range movable plate 30, when the extended-range lever 50 is rotated to make the extended-range movable plate 30 move along the extended-range slide rail 20, that is, the extended-range mechanism can also increase the effective stroke at the front and rear ends by rotating the extended-range lever 50 while following the movement of the power transmission mechanism, so as to be better suitable for projects with limited space volume to meet usage requirements.

[0033] In one embodiment, a range-extending movable block 60 is connected to the bottom of the range-extending movable plate 30 , and the range-extending movable block 60 is connected to the range-extending lever 50 .

[0034] Specifically, the bottom of the center of the range-extending movable plate 30 is connected with an extended-range movable block 60. The extended-range movable block 60 serves as a connection point to ensure that the extended-range movable plate 30 can be stably connected to the extended-range lever 50. This connection structure helps to reduce instability and vibration during movement, thereby improving the stability and reliability of the entire mechanism. In addition, when the range-extending lever 50 is rotated, the force and movement generated by the range-extending lever 50 can be transmitted to the extended-range movable plate 30 through the extended-range movable block 60, thereby driving the extended-range movable plate 30 to slide along the extended-range slide rail 20. This design enables the rotation of the extended-range lever 50 to be directly converted into the linear movement of the extended-range movable plate 30, thereby achieving effective motion conversion. In addition, by adjusting the position and connection method of the extended-range movable block 60 on the extended-range movable plate 30, the motion trajectory of the extended-range movable plate 30 can be optimized, which helps to ensure that the extended-range movable plate 30 can move along a predetermined path, thereby meeting application requirements. In addition, the design of the range-extending movable block 60 can increase the strength and rigidity of the entire range-extending mechanism, thereby improving its ability to withstand external forces and resist deformation. This design helps to ensure the stability and reliability of the range-extending mechanism under long-term or high-load operation.

[0035] In one embodiment, a waist-shaped groove 51 is provided on the range-extending lever 50 , and the range-extending movable block 60 is slidably connected to the waist-shaped groove 51 .

[0036] Specifically, the design of the waist-shaped groove 51 allows the extended-range movable block 60 to slide in the groove, so that the range of motion of the extended-range movable plate 30 can be adjusted as needed. This adjustability increases the flexibility and adaptability of the extended-range mechanism, enabling it to adapt to different work scenarios and needs. In addition, by accurately controlling the position of the extended-range movable block 60 in the waist-shaped groove 51, accurate control of the movement of the extended-range movable plate 30 can be achieved. This precise control helps to improve operational accuracy and stability, especially in applications that require high-precision operations. In addition, although the extended-range movable block 60 can slide in the waist-shaped groove 51, this sliding connection still provides a relatively stable connection. This stability helps to reduce instability and vibration during movement, thereby improving the stability and reliability of the entire mechanism. In addition, when it is necessary to adjust the range or position of the extended-range movable plate 30, it can be achieved by simply sliding the extended-range movable block 60 in the waist-shaped groove 51. This convenient adjustment and calibration method helps to improve the ease of use and maintainability of the equipment.

[0040] Specifically, the first support block 41 and the second support block 42 are arranged side by side to receive objects together; mounting blocks are arranged on both sides of the range-extending movable plate 30, and both sides of the support shaft 43 are respectively connected to the mounting blocks. The reset spring 45 is sleeved on the support shaft 43 and is respectively located between the first support block 41 and the limit block 44, and between the second support block 42 and the limit block 44; when external force acts on the support block, the reset spring 45 will be compressed; once the external force disappears, the reset spring 45 will quickly return to its original state to drive the support block back to its initial position. This automatic reset function enables the support assembly 40 to respond quickly to external changes, thereby improving the response speed and stability of the device.

[0041] In one embodiment, the first support block 41 and the second support block 42 have the same structure, and an upper follower 46 is disposed at one end of the first support block 41 away from the return spring 45 .

[0042] Specifically, the upper follower 46 is used to connect an object, that is, it is connected to the object on both the left and right sides, so that when the range-extending mechanism moves and brings the object to move, the object will not become loose.

[0043] In one embodiment, a lower follower 47 is disposed at one end of the first support block 41 away from the return spring 45 .

[0044] Specifically, when the external unlocking mechanism presses the lower follower 47 , the return spring 45 is compressed, so that the upper follower 46 is separated from the object, and then the return spring 45 drives the support block back to the initial position.

[0045] In one embodiment, a transmission connection block 11 is further provided on one side of the motion base 10 .

[0046] Specifically, the transmission connection block 11 is used to connect the power transmission mechanism to drive the moving base 10 to reciprocate in the front-rear direction.

[0048] Specifically, the driving assembly 82 is composed of a driving motor and a conveyor belt, and one side of the transmission connection block 11 is connected to the conveyor belt so that when the conveyor belt is working, it drives the moving base 10 to reciprocate in the front-to-back direction. The rear end of the conveying seat 81 is also provided with an unlocking assembly 85, which is used to squeeze the lower follower 47. The front end of the tray 90 is provided with a V-shaped groove 91, and the V-shaped groove 91 cooperates with the upper follower 46. In the actual application scenario, the rear end of the conveying mechanism 80 is provided with a silo, and several layers of trays 90 are placed in the silo from top to bottom, and each tray 90 is placed with materials. When the driving assembly 82 drives the moving base 10 to move to the rear end until the range-extending lever 50 abuts against the contact follower 84 at the rear end, the driving assembly 82 continues to work to rotate the range-extending lever 50, so that the range-extending movable plate 30 moves backward along the range-extending slide rail 20 until the upper follower 46 is engaged with the V-shaped groove 91, and then the driving assembly 82 drives the moving base 10 to move to the front end until the range-extending lever 50 abuts against the contact follower 84 at the front end. The follower 84 is used to move the extended-range movable plate 30 forward along the extended-range slide rail 20, and then the external manipulator takes away the material on the pallet 90, and then the driving component 82 drives the moving base 10 to move to the rear end until the lower follower 47 contacts the unlocking component 85, and then the unlocking component 85 squeezes the lower follower 47 to compress the return spring 45, so that the upper follower 46 is disengaged from the V-groove 91, so that the empty pallet 90 returns to the silo, and then the silo works to drive the empty pallet 90 downward and away from the operating station, and the new pallet 90 with materials placed on it descends to the operating station, and then the above operations are repeated.

[0049] Specifically, the unlocking assembly 85 is composed of a telescopic cylinder and an extrusion block. The telescopic cylinder is fixed to the conveying seat 81 , and the extrusion block is connected to the telescopic end of the telescopic cylinder.

[0050] In one embodiment, guide wheels 86 are disposed on both sides of the conveying seat 81 .

[0051] Specifically, a row of guide wheels 86 are provided on both the left and right sides of the conveying seat 81 . The guide wheels 86 are in contact with the lower surface of the tray 90 . During the movement of the tray 90 , the guide wheels 86 play a guiding role.

[0052] Among them, the pallet conveying device drives the range-extending mechanism to move through the driving component 82, and then the range-extending lever 50 abuts against the contact follower 84 to rotate the range-extending lever 50 and drive the range-extending movable plate 30 to move along the range-extending slide rail 20, so that the effective stroke of the support component 40 at the front and rear ends of the conveying seat 81 is increased, which can better accommodate the pallet 90, so as to be suitable for projects with limited space volume and meet usage requirements.
